Default braking shimmy mystery

My truck is an '06 4x4 and it was a salvage title front end damage. not enough to deploy the airbags. and the frame is straight as an arrow to my knolage.


OK so when I apply the brake I get a vibration.

I do NOT feel it in the brake pedal.
I do NOT feel it in the Steering Wheel.
I does seem to come and go a little.
I have had the rotors tuned and that did not help.
The tire Rods are new with only 2k miles on it.

This may sound wierd but if I am braking on slighly rough terain (like your average old pothole filled in road) I swear the vibration goes away.
It only seems to be there when I brake on smooth even road.

Any ideas where I should start to look? I'm planing on putting a leveling kit on it here in a couple of weeks so that would be a good time.

There was a recall on the front hubs, make sure it was performed.

Might be warped rotors, friend of mine has an 04 that does it bad. Had them turned and it didn't help. Heard of several trucks that it does it on. Search google for 'dodge ram brakes warp' and see if you get any hits.

Here is the recall. I drove an 06 that did not have it performed, it was bad.

You know there is also a TSB for the front lower control arm bushings that can cause a shimmy.

odd that a front end damage with no airbag dplymnt would call for a salvage title, esp since its an 06.

makes since, you cant feel the vibration because youre feeling the bumpy roads vibration.

Technical Service Bulletin, different from a recall in that it is mainly for the shops to diagnose common issues quickly.
